CASTING APPARATUS.

Application filed February 4, 1913.

T 0 all'whom '1' i may concern:

a. citizen of the l nited States. and a resident of l rcdericlr. in the county of Frederick and State of Maryland. have made cer' tain new and useful Improvements in (last ing Apparatus, ot which the 'lollowingis a specification.

My invention relates to improvements in casting apparatuses. and it consists in the combinations. constru tions. and arrange ments herein des ribed and claimed.

An object of mv invention is to provide an improved casting apparatus in which objects may be molded with great rapidit and at small cost.

A. further object of my invention is to provide an improved mold construction in which there are slidable and removal'ile mold sections to permit the -astin of objects of irregular shape.

A further object ot my invention is to pro vide a device arranged so as to permit the ready removal ot the article and the reasscmblinp; or the parts of the mold.

Other objects and advantages will appear in the following: specification and the novel teatures of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application in which- Figure 1 a plan view of the device. Fig. 2 is a vertical section through the mold, Fig. 3 is a face view of the central mold section, F g. 4 is a face view of one of the movable mold sections. Fig. 5 is a plan view of a modified form ot the device. Fig. (l is a section through the mold along the line 6 -6 of Fig. 5, Fig. 7 is a face view of one of the. movable mold sections shown in Fig. 5, Fig. 8 is a Vertical se tion through a modified form of mold, Fig. 5) is a side view of the mold shown in Fig. h. certain portions being shown in section. Fig. 10 is plan view of the mold shown in Fig. 55. l ll is a sectional view of another modified form of the mold, and Fig. 12 is a plan view of the mold sections shown in Fig. 8.

Referring now to Fig. l, I have shown therein a main. frame consisting of the end members 1 and the longitudinal rods 2 co 1- nccting them. Each of the end n'iembcrs Specification of Letters Patent.

3 hav ing a piston & and a piston rod 5. Inlet pipes 6 for motive fluid are connected by branch pipes 7 to each end of the c linders 3, the three-way cocks 8 being provided for admitting the motive fluid into either end of the cylinder so as to move the piston 4 in either direction. Carried by the rods 2 is a central mold se tion 9. This mold section is made of suitable refractory material and has a series ot pipes 10 embedded therein for the purpose of cooling the section. the drawings l have illustrated this central section as having" recesses .l l'or receiving the metal. The body portion the mold section fl is also provided with a. series of openings Sl arranged to receives cores ll which project into th recess s 9- as shown in Fig. 2. Arranged to be brought into close proximity to the mohl section 5) are the movable mold members 1'3 and 13 respectivelv. In Fig. 4; l have shown a face view of one of these movable members. It will be seen that it is provided with a cooling pipe l0 ot' the same nature as that already described in connection with the central mold member. Both the mold Illtll'lbQlS 12 and l? are movable along the guide rods 2. It will be seen that at the upper end of the mold members there is a space left for a removable section 14. This section is provided with a recess 15 which is contiguous to the recess 9*, and which receives metal. In this in stance a log is to be cast on the plate which is to be molded.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. The cores ll are inserted in the central mold member. The removable sections 1.4 are placed in position and since they are beveled in two di rections they will remain in this position. The corms 8 are now turned so as to cause the moi'able mold sections 12 and 13 to abut the outer sides of the central mold section. The mold is now ready for casting. c The metal is poured in at the gate by the branches 17 into the recesses 9 and 15. The water which is flowing through the cooling pipes 10 causes the mold to cool rapidly and when it has sufficiently cooled the stop cocks 8 may be turned so as to force the pistons in the opposite direction. them 16 and runs ire lugs such as those shown at 21 able mold inembei: 'lbe iatiohari' n'ol member is bown a! and the movable mold member at 12.

It will be seen that by providing removable mold sections the pat-ta may be cast rapidly and the (fflStlltfl's lnav be readily removed. The UPOllIlJ ot' the (litlerent mold sections greatly facilitates: the rapldlty with which the castings may be made.
